To @ZZ yw /Lom t may concern.'

Be it known that I, LoviiLL T. BRENIZER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Chalk-Line Reels, of which the following is a specifica tion.

My invention relates to improvements in chalk line reels.

The object of my invention is to provide a chalk line reel which is simple in construction, cheap to manufacture, durable, not liable to get out of order, which is light and easily carried in the pocket, and which may be readily disassembled for the purpose of attaching a new line to the drum or for removing a worn line.

The novel features of my invention are hereinafter fully described and claimed.

ln the accompanying drawing which illustrates the preferred embodiment of my nvention,

Figure 1 is an end elevation of proved chalk line reel.

Fig. 2 is a central vertical sectional view of the same, on the line 2 2 of Fig. 1.

Fig. 3 is a cross section on the line 3 3 0f Fig. 2.

Fig. 4 is a top view of the twoy casing shells disposed apart from each other.

Similar reference characters designate similar parts in the different views.

The casing comprises, preferably, two shells 1 and 2, the shell 1 being removably fitted in th-e shell 2, and provided with a transverse slot 3 in' which is fitted an oblong reinforcing member 4 which is provided with a peripheral groove in which the member 1 is fitted. The member 4: is provided with a longitudinal slot or opening 5 through which is adapted to be inserted a chalk line 6 or other similar device, which is attached at its inner end to a drum 7 mounted in the shell 1 on a horizontal shaft 8 which extends through and is rotatable in holes 9 and 10 provided centrally respectively in the shells 1 and 2. The shaft 8 has within the casing near one end a threaded portion 11 which is fitted removably in a screw-threaded hole provided in one end of the drum 7 at the center thereof. The other end of the drum 7 is provided with a central hole through which the shaft 8 eX- tends. The other end of the shaft 8 outside the shell 1 has pivoted to it by a transverse my impin 12 a crank 13 adapted to be swung from the operative position, shownin solid lines iii Fig. 2, to a locking position, shown in dotted lines in said figure, in which latter position, the outwardly extending arm of the crank 13 is adapted to enter any one of a series of holes 14 provided in the shell 1.

Suitable means for releasably holding the crank 13 in said two positions is provided. In the drawing I have shown for this purpose a U-shaped spring 15 having one arm fixed in a transverse hole in the shaft 8, the other arm of the spring being disposed in anl end recess 16 in the shaft 8, the crank 13 being mounted in said recess. The free arm of the U-shaped spring 15 is adapted to bear against one Hat longitudinal edge of the crank 13 to hold the crank in the operative position, and against the opposite edge of the c rank to hold the crank in the locking position.

The shell 2 is provided with an edge recess 17 adapted to receive the member 4; when the shells are slipped together to the operative position. Adjacent to the recess 17 on the periphery of the shell 2 is a spring clip which is adapted to receive thereunder and to releasably hold a portion of the chalk line 6.

In assembling the device, the shaft 8 is slipped through the center hole in the shell 1, after which the drum 7 with the chalk line 6 wound thereon, is slipped onto the shaft 8, the outer end of the chalk line being passed through the slot'. The threaded portion 11 of the shaft is then screwed into the threaded hole in the center of the drum 7. The chalk line 6 is wound on the drum in a direction such that it will be wound onto the drum when the drum is turned by rotation of the shaft 8 so as to tighten the shaft in the threaded portion of the drum. The shell 2 is then slipped onto the shell 1 with the member 4 fitted into the recess 17. The recess 17 properly locates the clip 18 with respect to the slot 5. The chalk line 6 will be slipped under the clip 18 to prevent the chalk line running ofll from the drum. The shaft 8 and drum 7 may be turned by the crank 13, when the latter is swung to the position shown in solid lines in Fig. 2. The U-shaped spring 15 releasably holds the crank 13 in the operative position. The crank 13 may be locked against turning by swinging it to the position shown in dotted lines in Fig. 2, in which position the outer end of the crank may. be inserted into an one of the holes 14, thus holding the cran 13 and shaft 8 from turning.

The shell l may be provided with a peripheral rib 19, in which the adjacent edge of the shell 2 may rest.

The U-spring 15 by bearing against opposite edges respectively-of the crank 18, re-` leasabl holds the latter in the operative and the loc zing positions.

I do not limit my invention to the struc-y ture shown and described, as modications, within the scope of the appended claims, may be madewithout departing from the spirit of my invention.

Vhat I claim is 1. In a chalk line reel, a casing, having in one end a hole and provided in each end with an axial opening, a shaft extending through and rotatable in said openings and provided at one end with a pivoted crank adapted to be swung from an operative position to a position in which it will enter said hole so as to hold the shaft from turning, means for holding the crank in either of said two positions, and a drum having means for attaching thereto a chalk line or similar n device mounted onand rotatable with the shaft n said casing.

2. In a chalk line reel, a casing having a peripheral `slot for receiving therethrough vmounted inthe casing on the shaft and ro" tatable with the shaft, the drum being adapted to have the chalk line secured thereto and hold the crank releasablyin either of said two positions.

3. In a chalk line reel, a casing having a peripheral slot for the passage therethrough of achallr line and provided with one or more holes, a shaft rotatably mounted in said casing and provided with a pivoted crank adapted to be swung from an operative position to a locking position, and in the latter position-being adaptedto enter one of said holes in the casing for holding the crank from turning, a spring which re- ]easably holds the crank iny either of said two positions, and a drum mounted on and rotatable with. the'shaft in the casing and adapted to have said chalk line attached thereto and wound thereon.`

In testimony whereof I have signed my name to this specification.
